How to Test Car Tire Pressure?
2 Answers
The method for testing car tire pressure is to use a tire pressure gauge or observe the dashboard to determine the tire pressure condition. The following are the effects of excessive tire pressure: 1. Impact on braking performance: The friction and adhesion of the tire will decrease, affecting braking performance. 2. Reduced comfort: It can cause steering wheel vibration and deviation, reducing driving comfort. 3. Decreased tire lifespan: It accelerates the localized wear of the tread pattern in the center of the tire, reducing its lifespan. 4. Impact on component lifespan: Increased body vibration indirectly affects the lifespan of other components.
Testing car tire pressure is quite simple. I usually just use a tire pressure gauge to get it done. First, park the car on level ground, preferably after it has cooled down for at least three hours, as tire temperature affects accuracy. For tools, I prefer a digital gauge—just remove each tire's valve cap, press the gauge onto the valve, and read the pressure; a manual one or the type found at gas stations works too. The standard pressure is usually listed on the driver's door frame or in the manual—for example, my car recommends 32 to 35 psi for both front and rear tires. Check all four tires, including the spare, to ensure consistent pressure. Underinflated tires waste fuel and affect handling, while overinflation increases the risk of a blowout. That’s why I make it a habit to check monthly—it saves money and keeps me safe.
